Bug#601357: iceweasel: After Upgrade Iceweasel loads a website that produces a 404 error

[Volkmar Wörner]

My startup.homepage_override_rule was set to 
http://%LOCALE%.www.mozilla.com/%LOCALE%/%APP%/%VERSION%/whatsnew/
which it was since ever I use Iceweasel, I never changed it.
It is an empty string when reset.
After resetting browser.startup.homepage_override.mstone and restarting, no 
page like this is displayed.
